Your challenge is to create a scenario that includes as many Westerns as possible. For example, the 1960 film The Alamo takes enough liberties with history to count as honorary AH. Fannin's men are defeated and wiped out during the siege of the Alamo rather than simply remaining in Goliad, the siege involves multiple attacks on the fort, and the final battle is far bloodier than OTL. The butterflies from this alternate Texas Revolution could make for a wilder and more chaotic West. What other Westerns could fit into such a TL?
